Skipper offer special transformers for various applications meeting customer specific requirements. The manufacturing range includes unit auxiliaries, station auxiliaries, system interconnecting transformers, transformers suitable for both induction and arc furnaces, rectifier transformers, double winding and multi taping transformers and earthing transformers.
the range of kva ratings for such applications starts from 300kva to 15mva, voltage classes 11 kv, 22kv & 33kv to all national & international customers.
the some of the transformers manufactured are of very special features like extended delta transformers to suit 12 pulse rectifier furnace transformers.
Epoxy Resin Cast Current And Voltage Transformers
The dry type instrument transformers have been a great success specially in heavily polluted surroundings. Epoxy cast instrument transformers are also available for outdoor application in special type of resins known as cycloaliphatic resins.
Oil Filled Current Transformers
Oil filled current transformers in high voltage applications are still the preferred ones due to cost advantages and easy availability of the technology. They are available in live and dead tank versions depending on the customers requirements. In measuring and protection applications they can be manufactured in single or multi-core as well as multi-tap designs. Tap changing can also be on primary or secondary, however due to convenience of low current and low voltage, secondary tap changing is now a days the preferred trend.
Vacuum Circuit Breakers
The skipper make outdoor vacuum switchgear type pcvcb, is an outdoors, structure mounted, easy to install, vacuum switchgear for use in 12/36 kv system. It is a porcelain-clad construction similar to conventional outdoor high voltage switchgear and is a gang operated triple pole circuit breaker fitted with reliable and well-proven vacuum interrupters. Adequate phase clearances and height have been provided to meet standards and safety requirements. It is suitable for direct connection to overhead supply lines.
the type pcvcb design incorporates a minimum of moving parts and simplicity of assembly assuming a long mechanical and electrical life. All fundamental advantage due to use of vacuum interrupters like low drive energy, light weight construction, virtually shock free performance leading to ease of erection and reduction of foundation requirement etc. Has been retained.
Isolating Switches (Is-01)
Disconnecting switches are used for isolation of system under fault conditions or carrying out the maintenance work without disturbing the main supply network. The disconnecting switches are made as per relevant standards and the customers specifications. They are made with and without earth switches with mechanical / electrical interlocks, manually or motorized operated mechanism, having capacity to interrupt line charging currents. The current carrying parts are made of electrolytic grade copper. The contacts are designed to provide discharge free supply. The arcing horns ensure that main contacts remain safe during opening and closing operations thus giving a longer life to the switch. The metal parts are surface treated for protection against rust. The switches are tested from approved labs for high short circuit currents.
Isolating Switches (Is-02)
Down the years we have been working to better the switches in operation. Bearings and bushes were standardized to reduce the torque. Most of the manually operated switches can be operated with less than 30 kg operating weight.
we have also provided solid core insulator in most of the models to ensure operators safety in the event of main insulators leakage.
Expulsion Type Drop Out Fuses (Etdof-01)
Drop out fuses are used for fault protections in rural electrification, distribution system, industrial units having medium voltage connections both as primary and secondary back ups. The drop out fuse should operate before the connected equipment i.e transformer gets damaged. Generally D.O. Fuses are used as switching device along with protection and operated with the telescopic insulated rods from the ground level.
The operation of drop out fuse is extremely violent. Once the fuse blows off, the arc restrikes till it is quenched. Even few cycles are sufficient to damage the current carrying parts and the barrel.Skipper over a period of time has acquired expertise in the manufacturing of drop out fuses to withstand such short circuit currents.
Expulsion Type Fuse Elements
The Fuse cut outs are important feature of todays system protection. Utilities spend handsome amount to ensure the reliable distribution of power supply backed by highly consistent and reliable system protection. When we talk of the fuse Cut Out the, fuse link forms the Heart of it. It is very important that the fuse links follow the specified characteristics to avoid any malfunctioning of the protective system. SKIPPER - SK Series fuse links ensure the elimination of any such mal functioning thus making it more reliable than others available in the market.
Transformer Control Panel
Transformer & associated equipments connected in the network is normally a complex and delicate system. The protection of system & people working around it, its reliable operation to meet the expectations of users is extremely important. Here comes the role of transformer rtcc (remote tap changer control panels).
complete designing form concept to commissioning is undertaken, keeping in view the simplicity & ease of operation, high reliability & timely performance. In the early stages of project, the requirements are known only in general sense. Skipper undertakes such development & designing, supply & commissioning to meet voltage ranges upto 132 kv class. We also undertake to supply control & relay panels for line feeders, transformers, bus couplers transfer breakers of various system voltages.
